Status list
Status = 1:
The operation is complete (loading/unloading/reloading, prepare change, change).
The parameters of FC 8 (FC TM_TRANS) "NewToolMag", "NewToolLoc", "OldToolMag" and
"OldToolLoc" must be parameterized to the tool target positions specified in the interface
(except for Prepare change). For further information, please refer to description of
parameters of FC TM_TRANS or general Section of tool management in the PLC.
1. In the case of loading/unloading/reloading, the tool has arrived at the required target
2. In the case of "Prepare change", the new tool is now available. The tool may, for
3. In the case of "Change" (spindle or revolver), the tools addressed in the interface have
Status = 2:
The "new" tool cannot be made available.
This status is only admissible in conjunction with the "Change tool" command. When this
status is applied, the PLC must be prevented from making a change with the proposed tool.
The proposed (new) tool is disabled by the tool management function in the NCK. A new
command is then output by the tool management with a duplo tool. The positions in
parameters "NewToolMag", "NewToolLoc", "OldToolMag", and "OldToolLoc" correspond to
the original tool positions.
Status = 3:
An error has occurred.
The tool positions must not have been changed. Any changes to the magazine positions
which have taken place in the meantime must be notified beforehand, for example, with
status = 105 via FC TM_TRANS. Only then will the tool positions be taken into account by
the tool management function.
Status = 4:
It would be better to position the "old" tool in the magazine position specified in parameters
"OldToolMag" and "OldToolLoc".
This status is permissible only in conjunction with preparation for tool change (change into
spindle). After this status has been transferred to the tool management in the NCK, the tool
management tries to take the specified magazine position into account in the subsequent
command. However, it can only do so if the position is free. Parameters "NewToolMag" and
"NewToolLoc" are not taken into account.

address. If the bit in the interface in DB 71.DBX (n+0).3 "position at loading point" is
enabled, status 1 cannot be used for the function termination. Status 5 must be used for
correct termination.
example, be positioned in a buffer (gripper). In some cases, the target (magazine,
location) of the old tool has been moved to the tool-change position after placement of
the new tool in a buffer. However, the old tool still remains in the spindle. The
preparations for a tool change are thus complete. After this acknowledgment, the
"Change" command can be received. The positions in parameters "NewToolMag",
"NewToolLoc", "OldToolMag" and "OldToolLoc" correspond to the current tool positions.
now reached the required target addresses.
The tool-change operation is thus complete.
